Kibblewhite takes a scientific "system" approach when designing their valve spring kits.
Each component is designed to work with the others as part of the complete system.
Kibblewhite's engineers use a proprietary design and simulation software, and draw on their 70+ years of design experience to create these systems.
Kibblewhite's design, simulation, and manufacturing processes insure compatibility of the valve spring's force and natural frequency with the cam profile, valvetrain mass, system harmonics, and the engine RPM.
Kibblewhite spring manufacturing partners are U.S.-based companies that are ISO certified.

KPMI choose to use C630 nickel bronze as a material to make valve guides because of its ideal characteristics for the application.
The 4 to 5 percent nickel content provides superior resistance to wear, and the approximately 80 percent copper content delivers outstanding heat conductivity.
Guide profiles are designed to have minimal effect on the airstream while maintaining critical cross sectional thickness in high temperature areas, promoting high performance and endurance.
The top portion of the guides are shortened when cam lift information is available at the time of design shows that an additional retainer to seal clearance is required.
